I myself would find 2FA bothersome for low importance services.  Whether
it's U2F or OTP, I would generally find it silly to have to carry
the hardware/software on me all the time or even use it when it's laying
right next to me, say, just to approve a comment on a blog.

But I guess if we go for SSO, it becomes a necessity to better protect
our passwords.
